I encountered flying ants on Spring Creek this past Friday. Fish we're going apeshit in the section I fished. I saw some #18-#20 BWOs so started with those and picked up a few fish, but didn't really generate much interest. I watched the water for a few minutes and also checked the streamside vegetation. Had a slight breeze blow and then I saw what I was looking for. Switched to #20 CDC Flying Black Ant and picked off or broke off (lost two hogs) almost all of the risers in my vicinity. Action was fast and furious for about 90 mins before shutting off. If someone needs a pattern, let me know and I'll post up my two recipes. Be sure to also carry these in cinnamon as I have seen those in the past as well.
